How Far Can We Drill? Temperature and Pressure in Earth's Interior

Run Time: 00:02:29

In a comparison of extreme drill holes to the diameter of the Earth, we see that even when reaching a depth of 14 km, geologists have barely scratched the Earth's surface. Geologists Andy Kurtz of Boston University, and Keith Klepeis of the University of Vermont, discuss temperature and pressure in the interior of the Earth and the obstacles that limit the depth to which we can drill.
